摘要： An example printing device composing a first printhead and a second printhead is described. In some examples the example printing device comprises a controller. The example printing device is to operate in a first operating mode in which the first printhead is to dispense a first printing substance, the first printing substance to transfer color via a first colorant transfer mechanism, and to operate in a second operating mode in which the second printhead is to dispense a second printing substance, the second printing substance to transfer via a second colorant transfer mechanism different to the first colorant transfer mechanism. An example controller is to cause the example printing device to operate in a selected one of the first and second operating modes.
